Schefflera Camille Cultivar Resistant to Spider Mites and Bacterial Leaf Blight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Schefflera actinophylla cultivars lack resistance to spider mites and bacterial leaf blight and leaf spot, and have thinner, lighter green leaves with longer internode lengths and faster growth rates, making them less desirable for ornamental use.
Innovation Solution
The new cultivar 'Camille' exhibits dark green, shiny, thick foliage with short leaf internodes, and demonstrates resistance to spider mites and bacterial leaf blight and leaf spot, achieved through asexual propagation by air layering and stem cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional Schefflera actinophylla cultivars are used, then faster growth rate is achieved, but resistance to spider mites and bacterial leaf blight is lost
Solution Approach 1:
The patent applies parameter changes by selecting and propagating plants with specific phenotypic characteristics (dark green shiny foliage, thick leaves, short internodes) that confer disease resistance. This involves changing the genetic parameters of the cultivar through selective propagation to achieve both slow growth and high resistance, resolving the contradiction between growth rate and disease resistance.
2Productivity
If conventional Schefflera actinophylla cultivars are used, then faster growth rate is achieved, but leaf thickness and darkness are reduced
Solution Approach 1:
The patent changes the phenotypic parameters of the plant by selecting for thick, dark green leaves with short internodes. This parameter change results in a more compact, ornamentally desirable plant form that trades faster growth for improved leaf quality and compactness.
3Length of moving object
If conventional Schefflera actinophylla cultivars are used, then longer leaf internode lengths are achieved, but ornamental value is reduced
Solution Approach 1:
The patent applies parameter changes by selecting for short internode lengths, which creates a more compact and ornamentally desirable plant structure. This parameter change reduces the overall size and creates a denser foliage pattern that is highly valued in ornamental gardening.
